I have a JVC DVD Receiver THG-41 Surround Sound System, I'm trying to watch stuff off my Segate Hard drive... But it wont register anything off it, it won't register anything coming from the USB port.

SOURCE: surround sound not working through ordinary tv

Try connecting the red and white audio cords to your system from your cable box/satellite receiver instead of your tv. Worked for me.

SOURCE: Setting up receive set top box and tv for surround sound

Plug the TV to an open channel on your receiver via this output:
*Rear, 1 x Digital audio output (coaxial) ( TOSLINK )
This will look like a single RCA output plug.
Set that input channel on your receiver to some sort of virtual surround mode because it doesn't look like your HDTV has a decoder in it (meaning it will come out stereo and the receiver will have to fake it).
Turn the volume all the way down on the TV and use the receiver to control TV volume just as you do with DVDs.

*Substitute this with the digital audio output on your set top box if you are sending video only to the TV from the set top box (component, DVI or s-video connections). So video goes to the TV, audio to the receiver.

I have had the same problem on my home theater maybe you should try to wiggle the speaker cord it could be loosly hooked up to your home theater

use your t/v audio out with RCA cables to your reciever input like(vcr in, dvd in, dtv in)
